Kinect finally went on sale in the UK this morning - six days after it hit shelves in the US.
However, stock levels are already causing problems, with some major retailers claiming that they have completely sold out of their first allocation of the device.
Kinect was granted a star-studded launch in London last night, at the iconic Natural History Museum Ice Rink.
Fans lined the streets outside the Museum as celebrities, media and competition winners were treated to exclusive performances from new boy band The Wanted and warbler Leona Lewis.
Kinect Sports, Kinect Adventures and Dance Central were on show at the event.
Thousands of people also queued at over 300 retailers around the UK for midnight launches. Those who queued for hours outside GAME's flagship store on London's Oxford Street were also granted a guest appearance by The Wanted.
Neil Thompson, General Manager of Microsoft's Entertainment and Devices Division (UK & IR), said: "We are delighted to put Kinect into people's living rooms and turn science fiction into science-fact. Kinect transforms games and entertainment experiences, offering an intuitive and simple way that everyone will enjoy."
Kinect launches in the UK today at £129.99 ERP for the stand-alone Kinect Sensor and Kinect Adventures game. The all-in one Xbox 360 Kinect Console Bundle - including the new Xbox 360 4GB console and Kinect Adventures - costs £249.99.
